You build the case WITH impeachment. The House sits as a Grand Jury. There is no burden of proof, but every charge can be named and evidence presented. You do not win a case before you make a case.

I'm talking about building the case with the public.
They don't even know the difference between impeachment and conviction.
Obama would certainly lose in a regular courtroom. He'll be a martyr, though, if he's impeached right now.
The best approach, IMO, is to first hold hearings about government corruption in general. Tie everything together -- voter manipulation by executive orders, government abuse against political opponents, outright lies concerning Benghazi to influence the 2012 election. Roll all the scandals into one and create in the mind of the public the correct impression that the entire administration from top to bottom is corrupt.
Once the public sees Obama as a Nixon, then impeach. We aren't there yet. The public generally still doesn't know enough about all the rotten things this administration has done -- only those of us paying attention do know.
